storybook-hmr - SKILL.md Agent Skill

name: storybook-hmr description: >- Apply or revert the local Storybook HMR patch that auto-rebuilds the UI package when source files change. Use when starting Storybook work, component modernization, or when the user mentions Storybook HMR or hot reload not working for UI components.

Storybook HMR Patch

Apply a local patch to storybook/vite.config.js that adds a file watcher for packages/ui/src/lib/. When any UI component source file changes, the watcher automatically runs pnpm --filter @podman-desktop/ui-svelte build to rebuild packages/ui/dist/, invalidates Vite's module cache, and triggers a full reload. Without this patch, editing UI component source files has no effect in Storybook because the imports resolve through the package exports map to dist/.

This patch is intentionally kept local and must never be committed or pushed. The upstream project has declined to merge it.

Patch location

Bundled with this skill:

.agents/skills/storybook-hmr/patches/storybook-hmr.patch

Apply the patch

/usr/bin/git apply .agents/skills/storybook-hmr/patches/storybook-hmr.patch

If the upstream file has changed and the patch no longer applies cleanly, use 3-way merge:

/usr/bin/git apply --3way .agents/skills/storybook-hmr/patches/storybook-hmr.patch

After applying, restart Storybook (pnpm --filter storybook dev).

Revert the patch

/usr/bin/git checkout -- storybook/vite.config.js

Before committing

Always revert the patch before committing or creating a PR. The patch should never appear in git history.

If the patch fails to apply

The upstream storybook/vite.config.js has changed too much. Regenerate the patch:

Read the current upstream storybook/vite.config.js
Apply the same changes manually: replace the colorRegistryWatcher function with a generic createFileWatcher factory and add the uiPackageWatcher call
Generate a new patch: /usr/bin/git diff --no-color -- storybook/vite.config.js > .agents/skills/storybook-hmr/patches/storybook-hmr.patch

The key changes the patch makes:

Extracts a createFileWatcher({ name, paths, ignored, command, invalidatePattern }) factory from the existing colorRegistryWatcher
Adds a second watcher for packages/ui/src/lib that runs pnpm --filter @podman-desktop/ui-svelte build on change
Invalidates Vite's module graph for packages/ui/dist entries before triggering reload

Important

Use /usr/bin/git (absolute path) for patch operations to bypass RTK proxy which mangles diff output
The patch does not touch package.json or lockfiles
